Message and Entry组件

from tkinter import *
msg = Message(text="Oh by the way, which one's Pink?")
msg.config(bg='pink', font=('times', 16, 'italic'))
msg.pack(fill=X, expand=YES)
mainloop()

from tkinter import *
import sys 
def fetch():
    print('Input => "%s"' % ent.get()) # get text
def quit():
    sys.exit()
root = Tk()
ent = Entry(root)
ent.insert(0, 'Type words here') # set text 插入一个原始默认的文本
ent.pack(side=TOP, fill=X) # grow horiz 获得水平增大
ent.focus() # save a click 保存单击事件
ent.bind('<Return>', (lambda event: fetch())) # on enter key  当按下回车键时触发
btn = Button(root, text='Fetch', command=fetch) # and on button 当按下按钮时触发
btn.pack(side=LEFT)
btn1 = Button(root,text='QUIT',command=quit)
btn1.pack(side=RIGHT)
root.mainloop()

ent.insert(0, 'some text') # set value 保存值
value = ent.get() # fetch value (a string) 获取值
ent.delete(0, END) # first, delete from start to end 清空值
ent.insert(0, 'some text') # then set value 插入值

表单

from tkinter import *
import sys
fields = 'Name', 'Job', 'Pay'
def fetch(variables):
    for variable in variables:
        print('Input => "%s"' % variable.get()) # get from var
def quit():
    sys.exit()
def makeform(root, fields):
    form = Frame(root) # make outer frame
    left = Frame(form) # make two columns
    rite = Frame(form)
    form.pack(fill=X)
    left.pack(side=LEFT)
    rite.pack(side=RIGHT, expand=YES, fill=X) # grow horizontal
    variables = []
    for field in fields:
        lab = Label(left, width=5, text=field) # add to columns
        ent = Entry(rite)
        lab.pack(side=TOP)
        ent.pack(side=TOP, fill=X) # grow horizontal
        var = StringVar()
        ent.config(textvariable=var) # link field to var
        var.set('enter here')
        variables.append(var)
    return variables
if __name__ == '__main__':
    root = Tk()
    vars = makeform(root, fields)
    Button(root, text='Fetch', command=(lambda: fetch(vars))).pack(side=LEFT)
    Button(root,text='QUIT',command=quit).pack(side=RIGHT)
    root.bind('<Return>', (lambda event: fetch(vars)))
    root.mainloop()

复选按钮

from tkinter import *
states = [] # change object not name
def onPress(i): # keep track of states
    states[i] = not states[i] # changes False->True, True->False
root = Tk()
for i in range(10):
    chk = Checkbutton(root, text=str(i), command=(lambda i=i: onPress(i)) )
    chk.pack(side=LEFT)
    states.append(False)
root.mainloop()
print(states) # show all states on exit

单选按钮

from tkinter import *
root = Tk()
var = StringVar()
for i in range(10):
    rad = Radiobutton(root, text=str(i), variable=var, value=str(i % 3))
    rad.pack(side=LEFT)
var.set(' ') # deselect all initially
root.mainloop()

from tkinter import *
state = ''
buttons = []
def onPress(i):
    global state
    state = i
    #print(buttons)
    for btn in buttons:
        btn.deselect()
        buttons[i].select()
root = Tk()
for i in range(10):
    rad = Radiobutton(root, text=str(i),
    value=str(i), command=(lambda i=i: onPress(i)) )
    rad.pack(side=LEFT)
    buttons.append(rad)
onPress(0) # select first initially
root.mainloop()
print(state) # show state on exit

标尺

from tkinter import *
root = Tk()
scl = Scale(root, from_=-100, to=100, tickinterval=50, resolution=10)  
scl.pack(expand=YES, fill=Y)
def report():
    print(scl.get())
Button(root, text='state', command=report).pack(side=RIGHT)
root.mainloop()

resolution=10 每次移动10个单位
tickinterval=50  间隔为50个单位

from tkinter import *
class Checkbar(Frame):
    def __init__(self, parent=None, picks=[], side=LEFT, anchor=W):
        Frame.__init__(self, parent)
        self.vars = []
        for pick in picks:
            var = IntVar()
            chk = Checkbutton(self, text=pick, variable=var)
            chk.pack(side=side, anchor=anchor, expand=YES)
            self.vars.append(var)
    def state(self):
        return [var.get() for var in self.vars]
class Radiobar(Frame):
    def __init__(self, parent=None, picks=[], side=LEFT, anchor=W):
        Frame.__init__(self, parent)
        self.var = StringVar()
        self.var.set(picks[0])
        for pick in picks:
            rad = Radiobutton(self, text=pick, value=pick, variable=self.var)
            rad.pack(side=side, anchor=anchor, expand=YES)
    def state(self):
        return self.var.get()
if __name__ == '__main__':
    root = Tk()
    lng = Checkbar(root, ['Python', 'C#', 'Java', 'C++'])
    gui = Radiobar(root, ['win', 'x11', 'mac'], side=TOP, anchor=NW)
    tgl = Checkbar(root, ['All'])
    
    gui.pack(side=LEFT, fill=Y)
    lng.pack(side=TOP, fill=X)
    tgl.pack(side=LEFT)
    lng.config(relief=GROOVE, bd=2)
    gui.config(relief=RIDGE, bd=2)
    def allstates():
        print(gui.state(),lng.state())
        #print(gui.state(), lng.state(), tgl.state())   分别显示 win..,python...,all三个状态


    Button(root, text='Peek', command=allstates).pack(side=RIGHT)
    root.mainloop()

用entry设计表单

from tkinter import *
fields = 'Name', 'Job', 'Pay'
def fetch(entries):
    for entry in entries:
        print('Input => "%s"' % entry.get()) # get text
def quit():
    sys.exit()
def makeform(root, fields):
    entries = []
    for field in fields:
        row = Frame(root) # make a new row
        lab = Label(row, width=5, text=field) # add label, entry
        ent = Entry(row)
        row.pack(side=TOP, fill=X) # pack row on top
        lab.pack(side=LEFT)
        ent.pack(side=RIGHT, expand=YES, fill=X) # grow horizontal
        entries.append(ent)
    return entries
if __name__ == '__main__':
    root = Tk()
    ents = makeform(root, fields)
    root.bind('<Return>', (lambda event: fetch(ents)))
    Button(root, text='Fetch',command= (lambda: fetch(ents))).pack(side=LEFT)
    Button(root,text='QUIT',command=quit).pack(side=RIGHT)
    root.mainloop()
